Primary biliary cirrhosis, sometimes called PBC, is a disease in which the bile ducts in your liver are slowly destroyed. Bile, a fluid produced in your liver, plays a role in digesting food and helps rid your body of worn-out red blood cells, cholesterol and toxins.

When bile ducts are damaged, as in primary biliary cirrhosis, harmful substances can build up in your liver and sometimes lead to irreversible scarring of liver tissue (cirrhosis).

Primary biliary cirrhosis is considered an autoimmune disease, in which the body turns against its own cells. Researchers think it is triggered by a combination of genetic and environmental factors. Primary biliary cirrhosis usually develops slowly and medication can slow its progression, especially if treatment begins early.
